Description

A kind of automatic detection at circuit devcie angularity method and device
Technical field
The present invention relates to integrated circuit device angularity inspection technology fields, and especially a kind of automatic detection is at circuit device The method and device of part angularity.
Background technique
In hyundai electronics manufacturing industry, the manufacturing process of electronic component and the encapsulation process of integrated circuit, unavoidably To use to techniques manufacture means such as machine-shapings, the surface treatments such as chemical process, machining, hot-working;It was encapsulating Cheng Zhong arrives greatly various types of substrates, is needed between the small variety classes device to bare chip using differences such as cementing or welding Technique packaged type.Therefore in the manufacturing process of electronic component and the encapsulation process of integrated circuit, a large amount of machinery is answered Power, temperature stress and material are equipped with stress etc. and are introduced into electronic component, cause the deformation failure of component, and then seriously affect The function of integrated circuit is realized.
With the rapid development of electronics industry, the microminaturization of the device in large scale integrated circuit is necessarily becoming for development Gesture, the micromation of IC products and large-scale mean that density of components is higher.To the carry out office of high-density device It is that can not obviously implement that hand dipping device deformation in portion's, which is unable to satisfy manufacture demand again,.In face of such status, how In time, it is efficient must find in IC products encapsulation front and back component by the failure conditions such as stress deformation be realize it is highly reliable, High consistent, high efficient production IC products important leverage.Common detection device is can not be quickly directly to will seal The residual stress in component that dress and encapsulation are completed carries out detection characterization.But the release approach of stress is the deformation of material, It can may determine that the component with the presence or absence of deformation, therefore, it is determined that whether being failure by measuring the deformation angularity of component Part.Therefore, it is badly in need of the automatic detection of energy non-destructive testing and characterization electronic component angularity in high-end integrated circuit manufacturing field The method of angularity efficiently quickly realizes that the failure to integrated circuit automated production material and IC products deforms Detection and judgement, to improve the yield rate and reliability of product.In current automatic testing method, not for electrical member The automatic method of device angularity only just carries out Tracing back of quality questions in product when something goes wrong, searches reason, produce at this time Product have been completed, and can only be scrapped, and a large amount of man power and material is wasted.
Summary of the invention
The primary purpose of the present invention is that providing the automatic inspection of a kind of energy non-destructive testing and characterization electronic component angularity Angularity is surveyed, efficiently quickly realizes the inspection of the failure deformation to integrated circuit automated production material and IC products Survey and determine, thus improve product yield rate and reliability automatic detection at circuit devcie angularity method.
